Title: Improvements in or relating to the manufacture of high molecular weight linear polyamides
Inventor: FERRIER DUNCAN CAMERON
IPC: C08G69/04
Filed: 1964-09-26
Abstract: The molecular weight of polyamides as defined below is increased by a continuous process in which the polymer is heated and agitated for 10-60 minutes at a temperature above its m.p. and 260 DEG  C. during which time it is maintained in the form of an unsupported filament under an atmosphere having a water vapour pressure not exceeding 10 mm. Hg for a number of seconds not less than the quotient obtained by dividing the surface area of the filament in square decimeters by its volume in c.c.  The starting polyamides are defined as those derived by elimination of 96% of the theoretical water of condensation from a mixture of a diamine of formula NH2-X-NH2 and a dicarboxylic acid of formula HOCO-Y-COOH or an amino-acid of formula NH2-Z-COOH, wherein X is a chain of p+4q methylene groups or p-methylene groups and q phenylene groups, Y is a chain of r+4s methylene groups or r-methylene groups and s-phenylene groups, Z is a chain of t+4u methylene groups or t-methylene groups and u phenylene groups, q and s=0-2 at least one of them being 1 or 2, u=1 or 2, p=at least 2 but at least 6 if q is 0, r=at least 4 if s=0, p+r=at least 6 and t at least 3.  Numerous monomers are specified including hexamethylene diamine, adipic acid, m-xylene diamine, p - (b  - carboxyethoxy) - g - phenylpropionic acid and copolyamide forming mixtures thereof. The atmosphere having a water vapour pressure not exceeding 10 mm. Hg may be an inert gas stream, e.g. N2.  In one embodiment of the invention the untreated polyamide falls from a spinneret in the form of molten filaments into a pool of the molten polymer from which the finished product is withdrawn.  In another embodiment a stream of the initial polyamide is allowed to collect into a pool which is stirred. Polyamide from this pool is pumped up a pipe and through a spinneret above the liquid surface and the filaments issuing from the spinneret are allowed to fall back into the same pool from which the final product is withdrawn.  The product may have an intrinsic viscosity of at least 0.7 and a fatigue resistance of at least 60% strength retention.

Abstract: 1,241,843. Gyromagnetic resonance spectrometers. VARIAN ASSOCIATES. Aug.20, 1968 [Aug.21, 1967(2)], No.39742/68. Heading G1N. The operating parameters of a gyromagnetic resonance spectrometer 1 are automatically adjusted under the control of a computer 2 which stores in its memory the results of scanning a reference resonance line or whole spectrum for different settings of the operating parameters and derives correction signals which are applied to adjust the operating parameters of the spectrometer. Individual parameters are adjusted as follows:- Field homogeneity. The currents in field homogenizing coils 12, 13 are adjusted to give maximum resonance peak height or maximum area under resonance curve with forced or free precession with the spectrometer locked on to a given reference resonance line or with repetitive scanning of a reference resonance line or spectrum. If free precession is used, a "dephasing pulse" may be applied between successive resonance measurements. Alternatively, the adjustments may be made to give minimum width of peak or maximum peak-to-peak of first wiggle of resonance. Field Stability. The polarizing field is adjusted to give maximum correlation between successive spectra or to superimpose one spectrum on another or to give zero beat frequency between a free precession signal and the r.f. exciting signal or another stable frequency. Radio Frequency Phase. With the spectrometer locked on to a given reference line, the phase of the r.f. transmitter is adjusted so that with pulsed excitation the initial value of the dispersion mode signal is zero or the initial value of the absorption mode signal is a maximum. Alternatively, with repetitive scanning of a line or spectrum, the phase is adjusted to give maximum peak height, maximum peak area or maximum peak symmetry. Radio Frequency Intensity. The intensity of the r.f. transmitter is adjusted to give maximum peak height with repetitive scanning of the spectrum. Scanning Rate. The scanning speed may be slow when the resonance signal is above a given value and fast when the resonance signal is below the given value. Alternatively, correction signals may be derived from side-bands of a given reference line or the rate-of-change of a beat frequency between a strong free induction resonance and the r.f. signal. Filter time-constants. These are adjusted during repetitive scanning of a spectrum to give maximum peak height or twice the minimum peak width or to eliminate wiggles from a reference line. Sample Spinning Rate. This may be adjusted to give maximum energy of a resonance line under pulsed r.f.; or maximum peak height or area or peak-to-peak height of first wiggle during repetitive scanning. Double Resonance Transmitter. The frequency of the double resonance r.f. transmitter is adjusted to give maximum effect and its intensity is adjusted to give maximum peak height when locked on to a reference line.

Abstract: 959,565. Locating cable faults. A. C. COSSOR Ltd. Nov. 18, 1960 [Nov. 24, 1959], No. 39910/59. Heading G1N. A break in an inaccessible conductor, which is disposed in a plurality of series-connected sections extending alongside one another, is located and repaired by applying a potential difference between the conductor terminals, exploring the electric potential along lines parallel to, or transverse with respect to, the sections to locate a region where there is a rapid change of potential, obtaining access to that section of the conductor which passes through this region, and repairing the break. The potential above a concrete floor in which a broken heating cable 10 is embedded, when A. C. source 14 is connected between its terminals, is explored by a capacitive probe (Fig. 2, not shown) which is also disclosed, and claimed, in Specification 959,566. An abnormally rapid potential variation of the probe is obtained for movement in direction 16 whenever the probe passes over the broken section b, and for direction 17 when the probe, being moved in a linee.g. 15-adjacent the broken section b, passes over the vicinity of the break. If the lay-out of the conductor is not known, it may be determined by a preliminary exploration in which the potential troughs which occur midway between each pair of adjacent sections, for any transverse movement of the probe, are mapped on the floor.

Abstract: An electric conductor comprises one or more wires of an alloy containing not less than 91% by weight of aluminium and 0.04 to 0.3% of tin as the essential constituents, the tin being in solid solution in the aluminium to substantially the maximum degree. The alloy may also contain one or more of the following elements within the ranges shown: .boron.0.001-0.05 .magnesium.0.001-7 .zirconium.0.001-0.3 .bismuth.0.001-0.3 .indium.0.001-0.5 .zinc.0.001-0.05 .copper.0.001-0.01 .silicon.0.001-0.2 .manganese.0.001-0.1 and may also contain up to 1% each of one or more elements having a solid solubility in aluminium of less than 0.03% when measured at 1180 DEG F. or below.  The desired structure may be obtained by homogenizing the cast alloy, preferably at 1000 to 1180 DEG F. for 15 minutes to 24 hours, to dissolve the maximum amount of tin, and then cooling it at not less than 25 DEG F./hour, either to the second stage treatment temperature in the range 600 DEG  to 800 DEG F. or to room temperature, after which it is subsequently reheated to the second stage temperature.  The alloy is held at that temperature for 10 minutes to 6 hours, and is then processed conventionally, as by hot rolling to rod and then drawing to wire of the desired diameter.  As exemplified the latter may then be stranded over a galvanized steel core.

Abstract: 1,183,836. Thin layer chromatography. MAY & BAKER Ltd. 20 Aug., 1968 [4 Sept., 1967], No. 40357/67. Heading B1X. Plates for use in thin layer chromatography, suitably made of glass or synthetic resin, carry one or more concave grooves 13, 14 adjacent one edge or two opposite edges. The plates are coated with a uniformly planar layer of absorbent 12, suitably of silica with calcium sulphate as binder, so that absorbent wholly fills the grooves which are preferably 0.5-1.5 cm. wide and 1-3 mm. in maximum depth. In use, material to be analyzed is applied along the line of a groove or along a line parallel thereto between the groove and an adjacent edge; the chromatogram may then be developed directly by standing the plate in a shallow tray of solvent with the groove parallel to the surface (see Fig. 3, not shown). Where undesired debris is present, however, a volatile solvent may first be used to establish a new origin front, after which the volatile solvent is allowed to evaporate and the plate developed as before. This latter technique is of value in estimating pesticide and herbicide residues from macerated animal and plant residues.

A voltage or current regulator includes a series control device which is protected from excessive dissipation by a protection arrangement responding to the sum of voltages derived from the current through the device and the voltage across the device. As shown, a voltage regulator comprises input terminals 10 and a series device 12 controlled in known manner over an amplifier 16 to maintain a constant voltage at output terminals 11. The impedance of the device 12 is also controlled by the output of an amplifier 18 which receives a first input proportional to the load current and derived from a resistor R, and a second input proportional to the voltage across the device 12 and derived from a voltage divider R1, R2; the amplifier 18 is arranged to be ineffective if its input is less than a critical value, but if this value is exceeded, amplifier 18 overrides the control effected by amplifier 16 and thereafter controls the device 12 to prevent excessive dissipation in the device. Backing voltage source 20, which may relate to the input voltage of the regulator, and a diode 21 determine the minimum voltage across the device 12 necessary to cause a voltage to be developed across resistor R1. The devices 12, 16, 18 may comprise transistors, and the devices 14, 20 may include Zener diodes, Fig.4 (not shown). Modifications are described with reference to Figs. 5, 8 and 9 (not shown). The circuit may be modified to maintain a constant current output by omitting the voltage controlled amplifier 16.
